The Pitch Of A Roof Is Its Slope

So the pitch would be the slope which would be the rise overrun.
The pitch of a roof is its slope. Although the terms pitch and slope are often used interchangeably they have two different meanings. The pitch of a roof is its vertical rise over its horizontal span. We re finding the pitch of the roof and we know that the rises six feet over a run of 10 feet. 8 feet by 15 feet log on.
A roof that rises 4 inches for every 1 foot or 12 inches of run is said to have a 4 in 12 slope. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. The pitch is the measurement of the rise of the roof to the span of the roof and is expressed as a fraction. Slope is the incline of the roof expressed as a ratio of the vertical rise to the horizontal run where the run is some portion of the span.
This ratio is always expressed as inches per foot. The pitch of a roof is its slope find the pitch of the roof shown. However most often a ratio of pitch also fraction is slang used for the more useful slope of rise over run of just one side half the span of a dual pitched roof. So that would be six over 10 and that would be 3 5.
